DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal finishing method for a synthetic resin baseboard and a synthetic resin flooring.

[0002]

2. Description of the Related Art Generally, a baseboard is often provided below a wall of a building. The skirting board includes a wooden board-shaped skirting board and a synthetic resin sheet-shaped skirting board. When a synthetic resin flooring is laid, a synthetic resin sheet-shaped skirting board is often used. As such a synthetic resin sheet-like baseboard,
For example, one having an R-shaped bellows at the end on the floor side is used. Usually, skirting boards are rarely joined to flooring,
Waterproofing and antibacterial properties are required in places such as washrooms and toilets that use water for cleaning, and in places such as hospitals and nursing homes where welfare facilities are used. The material was welded with a welding rod to perform a water stop treatment. Further, as a simple water stopping method, a silicone-based sealing material is filled on the back surface (wall surface side) of the R-shaped tongue of a synthetic resin sheet baseboard.

[0003]

The method of welding a skirting board and a flooring material using the above-mentioned welding rod has no problem in water stoppage, but if there is unevenness (unevenness) in the groundwork, the flooring material and the skirting board are not bonded. Is not constant, the welded portion meanders. Furthermore,
Welding with a welding rod at the corner was a very difficult and skilled operation. Moreover, since the excess portion of the welding rod cannot be cut after welding, a convex step is generated in the welded portion, and dirt and dust easily accumulate between the convex portion and the corner portion of the baseboard. It was not a good finish for hygiene.

A method of filling a silicone-based sealing material into the back surface of the base slab of the baseboard is to check the adhesion of the silicone to the synthetic resin floor material because the silicone has a small adhesive strength and the backside of the baseboard. However, it was not possible to completely seal the gap between the floor material and the baseboard or the groundwork, and the method was not excellent in waterproofness. The present invention solves these problems,
It is an object of the present invention to provide an end finishing method for baseboards and flooring materials that is excellent in water stoppage, workability, bonding strength, and aesthetic appearance.

[0005]

Means taken by the present invention to solve the above-mentioned problem is that a synthetic resin baseboard having an R-shaped bellows at the end on the floor side is attached to the lower part of the wall surface to form an R-shaped board. A velvet is superimposed on the surface of the synthetic resin flooring material, and the liquid epoxy sealing material is filled over the side end of the baseboard side and the synthetic resin flooring material and exposed to the surface, Joining the synthetic resin baseboard and the synthetic resin flooring, and separating the joint between the synthetic resin baseboard floor end and the synthetic resin flooring wall end. The joint is filled with a liquid epoxy-based sealing material, and the synthetic resin baseboard and the synthetic resin flooring are joined.

[0006]

According to the present invention, by the above means, the joining (adhesion) between the synthetic resin baseboard and the synthetic resin flooring material is strong, the water-stopping property is improved, and the joining can be easily performed without skill. . Also, there is no generation of a convex portion as in the case of using a conventional welding rod, and no accumulation of dirt or dust in the corners.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the accompanying drawings. A floor end of a synthetic resin sheet-like baseboard A on the floor surface side and a floor material B made of synthetic resin are bonded to a liquid epoxy sealing material C. It is finished by bonding. Examples of the shape of the synthetic resin sheet-like baseboard A include a structure in which an R-shaped bellows a is provided at an end of the baseboard on the floor surface side, a plate-shaped structure having no R-shaped bellows, and the like. Structural baseboards can also be used. The height of the baseboard A is preferably in the range of 50 to 400 mm, and the thickness thereof is preferably in the range of 0.5 to 5 mm. However, the present invention is not limited thereto.

The baseboard A is made of a synthetic resin sheet. Examples of the synthetic resin include polyvinyl chloride resin, polyethylene resin, polypropylene resin, polyester resin, ethylene-vinyl acetate copolymer resin and ethylene-ethyl acrylate resin. A thermoplastic resin such as a polymer resin, an ethylene-methyl acrylate copolymer resin, a polyurethane resin, or a so-called thermoplastic elastomer having a hard phase and a soft phase can be used. These synthetic resins can be appropriately mixed and used, or known additives such as a plasticizer, a stabilizer, a filler, an ultraviolet ray inhibitor, an antistatic agent, an antioxidant, a flame retardant, a lubricant, and a foaming agent can be appropriately compounded. It is also possible. Also, since the workability such as followability to the floor base surface or wall surface and the workability at the time of bonding, or the sheet-like baseboard is made into a roll shape to make it long, the baseboard is made of a soft synthetic resin sheet. It is preferred to use In order to make the sheet soft, a liquid plasticizer may be mixed with the synthetic resin, or a synthetic resin such as an ethylene-vinyl acetate copolymer resin, which is itself soft, may be used alone or as a mixture, or may be heated. A plastic elastomer can be used.

In the present invention, the method of joining the synthetic resin flooring A end on the floor side and the synthetic resin flooring B with the liquid epoxy-based sealing material C is described below. In the case of having the R-shaped bellows a, the tip of the R-shaped bellows a, that is, the side end on the floor side of the baseboard A is overlapped with the surface of the synthetic resin flooring B as shown in FIG. A liquid epoxy-based sealing material C is filled between the tip of the R-shaped bellow a and the synthetic resin floor material B and exposed to the surface, and the baseboard A and the floor material B are firmly bonded. . In the case where the baseboard is plate-like with no velvet, as shown in FIG. 2, the baseboard A is placed on the floor 1 and the end of the floor material B on the wall side is spaced apart from the wall 2 so that A, and a joint is filled with the sealing material C. Alternatively, as shown in FIG. 3, a floor material B is laid up to just two wall surfaces and an end of the baseboard A on the floor surface side. A joint is provided between the floor material and the floor material B, and the joint material is filled with the joint. Alternatively, as shown in FIG. 4, a joint is provided between the floor-side end of the baseboard A and the floor 1 and between the wall-side end of the floor material B and the wall 2, and the sealing material C is attached to the joint. Fill.
The baseboard A is adhered to the lower portion of the wall 2 with a vinyl acetate adhesive, a nitrile rubber adhesive, or the like.

The synthetic resin flooring B is generally a long sheet-like flooring or tiled flooring having a thickness of 1 to 6 mm, and the synthetic resin forming the flooring is the synthetic resin forming the baseboard. And the same material as the additives.

The sealing material C used in the present invention uses a liquid epoxy-based sealing material which has a large adhesive strength between the synthetic resin flooring B and the baseboard A, and is hardened and stain-resistant after sealing. The baseboard A is bonded to the material B. This epoxy-based sealing material may be any of a one-component type and a two-component type, and may be any of a solventless type, a solvent type and an emulsion type. The two-component sealing material is used by mixing a curing agent such as a polyamine and a polyol with an epoxy base material.

Such a liquid epoxy sealing material C
When the end of the baseboard A on the floor side is in contact with the flooring B as shown in FIG. 1, a step is preferably prevented between the end of the baseboard A and the flooring B as much as possible. It is preferable to perform the filling, and it is preferable to mask the periphery of the sealing material filling portion in order to make the finish a clean straight line. When filling the joint between the baseboard A and the flooring material B with the sealing material C as shown in FIGS. 2 and 3, the sealing material should be sealed so that the sealing material does not protrude as much as possible, or as shown in FIG. It is preferable to fill the sealing material so as to chamfer the corner. Also in these cases, it is preferable to make a beautiful finish by masking. The sealing material C can be arbitrarily colored, and can be colored according to the color of the floor material and the baseboard, or can be colored in a color different from that of the baseboard and the flooring to give an accent. .

Considering the replacement of the floor material for some reason at a later date, a non-woven fabric or a film with a film is stuck on the ground surface under the corners of the floor 1 and the wall 2 at the corners.
When the flooring material and the baseboard are adhered on it and the sealing material is filled, the sealing material can be removed at the same time by peeling off the nonwoven fabric or film from the base, and the workability is improved when replacing the flooring material. .

In joining the baseboard A and the flooring B,
It is also possible to perform welding by using an organic solvent capable of dissolving the synthetic resin constituting the floor material and the baseboard, and then filling and joining the sealing material. For example, when the floor material or the baseboard is a sheet made of a vinyl chloride resin, it is preferable to use a solvent mainly composed of tetrahydrofuran having a large dissolving power. In the case of welding with a solvent, it is necessary to provide a certain width of the end of the baseboard in contact with the flooring material, and it is preferable that the end of the baseboard be in contact with the flooring material with a width of 0.5 mm or more.

In the present invention, in places where antibacterial properties are required, an antibacterial agent and a fungicide can be added to the baseboard and flooring material, and an antibacterial agent can be appropriately added to the sealing material. As the antibacterial agent / antifungal agent, known agents can be used. For example, oxybisphenoxyarsine, 2,4,4′-trichloro-2′-hydroxydiphenyl ether, benzyl bromoaceerate, orthophenylphenol, or silver ion Antibacterial agents and antifungal agents comprising a series of compounds. Also, when conductivity and antistatic properties are required, a conductive material and an antistatic agent can be appropriately added to the sealing material. Known materials can be used for both the conductive material and the antistatic agent. Examples of the conductive material and the antistatic agent include a carbon-based conductive material such as carbon black, a metal powder such as tin oxide and aluminum, other surfactants, and polypyrrole.

Next, a concrete construction example of the present invention will be described. A long floor material made of a soft vinyl chloride resin having a thickness of 2 mm and a width of 1800 mm was laid on the floor surface, and a sheet-shaped baseboard made of a soft vinyl chloride resin having a height of 100 mm and having an R-shaped bellow was attached to a lower portion of the wall surface. . Next, the end of the baseboard on the side of the R-shaped tongue is overlaid and joined to the floor material surface. Use a liquid epoxy-based sealing material, fill the baseboard so that the side edges on the floor side are hidden, and do so so that there is no step on the floor material surface. The edges were firmly adhered to the surface of the flooring. In addition, the color of the flooring material was dark blue, the baseboard was dark brown, and the sealing material was colored dark blue according to the color of the flooring material.

[0017]

According to the present invention, by joining a synthetic resin flooring and a synthetic resin baseboard with a liquid epoxy-based sealing material, the welded portion rises as in the case of welding with a welding rod and enters the corner. There is no accumulation of dust and dirt,
Furthermore, even if there is unevenness in the groundwork and the joints meander,
Since the sealing material is in a liquid state, it is possible to cover the meandering portion and perform sealing in a straight line, so that the appearance can be beautifully finished. In addition, since welding with a welding rod is welding at the corners, welding was difficult and required skill, but joining with a sealing material can be easily performed because it is in a liquid state, and moreover, like a welding rod. In addition, the workability was greatly improved without the necessity of performing the work of shaving off the convex portion of the welding rod after welding. In addition, the terminal finishing method of the present invention can check the bonding state from the front side, so there is no problem such as a method of filling a silicone-based sealing material into the corners on the back of the baseboard, and the water stopping property, bonding A strong terminal finish is obtained.

[0018] A synthetic resin baseboard having an R-shaped bellows at the end of the floor surface is attached to the lower part of the wall surface, and the end of the R-shaped bellows is superimposed on the surface of the synthetic resin flooring material. Filling it with an epoxy-based sealing material makes it firmly adhered, affixes a synthetic resin baseboard to the lower part of the wall surface, provides a gap between the ends of the synthetic resin floor material, and provides a joint. Filling with epoxy-based sealing material and joining the baseboard and flooring, the workability is easy and the finish is extremely excellent, the joining strength is extremely high, and the waterproofness of the joint is even better. Become.
